DUTCH SLOUGH TIDAL RESTORATION MCCORMACK WILLIAMSON TRACT FLOODPLAIN AND TIDAL RESTORATION DWR Delta Levees Program DWR Division of Flood Management

This long-planned effort in an area formerly slated for urban development, will soon become Offering opportunities for restoration of critical tidal freshwater marsh and floodplain habitat, this 1,000+ acres of critically needed habitat for fish and wildlife in the Delta. The project’s location 1,600-acre island is immediately downstream of the confluence of the Cosumnes and Mokelumne in the western Delta offers a unique combination of the appropriate soil types and lack of Rivers. Flood flows and high-water conditions in this area threaten levees, bridges and roadways subsidence needed to create a large area of tidal marsh and complex intertidal channels. Native – as demonstrated by the unplanned levee breach on the site in 2017. The project will reduce grasslands and riparian forests will also be restored in the upland portions of this site. By flooding and provide aquatic and floodplain habitat along the downstream portion of the Cosumnes restoring these habitats that have historically dominated the Delta, this project will contribute Preserve by modifying levees on McCormack-Williamson Tract and Grizzly Slough. A key aspect of to the improvement of the overall ecological health of the Delta. This restoration effort will the DWR North Delta Flood Control and Ecosystem Restoration Project is to provide flood control provide habitat for native fish and wildlife species including Chinook salmon, giant garter snake, improvements while benefiting to the ecosystem and fish and wildlife. This project will create tidal and California black rail. After 15+ years of planning and permitting, construction will begin in marsh, subtidal, and floodplain/riparian habitats to restore natural ecological function. After more 2018 on two-thirds of the site, totaling 650+ acres of tidal and subtidal habitat. than a decade of planning and permitting efforts, construction will begin this year on Phase One, which includes constructing a new levee protecting existing infrastructure before breaching the site to restore tidal function in Phase Two of construction. HILL SLOUGH TIDAL RESTORATION Department of Fish and Wildlife (DFW) FREMONT WEIR ADULT FISH PASSAGE Department of Water Resources (DWR) and U.S. Bureau of Reclamation Located along the northern margin of Suisun Marsh on DFW’s Hill Slough Wildlife Area, this project will restore brackish tidal marsh and associated upland ecotone. The project involves the This project addresses a long-standing source of migratory delay to, and loss of, special status restoration of 600+ acres of tidal marsh to aid in the recovery of listed plant and wildlife species fish species during migration upstream through the Delta to the Sacramento River. The current while contributing to primary productivity in the estuary and reducing the entrainment of at-risk fish ladder at the Fremont Weir provides insufficient passage for adult salmon and no passage for native species as well as other resident and transitory fish species in the Suisun Bay. Implemented adult sturgeon. Improving fish passage is necessary to enable open channel upstream migration to by DFW, the site will increase the ability of the Suisun Marsh to adapt to sea level rise and provide allow fish to ultimately reach their spawning areas. Construction will begin in 2018 to widen and public access for recreational activities adjacent to Suisun City. Road improvements and interior deepen the existing Fremont Weir fish ladder as well as modify and remove earthen agricultural site work will begin in 2018, with all inwater construction work taking place in 2019. road crossings along the Tule Canal to allow for adult fish passage. The project will provide upstream fish passage during and immediately after flood flows overtopping the weir.
